   The magnetron, which generates the microwaves, is the heart of the oven. Midsized and large ovens are rated at 850 to 1,650 watts; compact ovens, at 600 to 800 watts. More watts mean more heat.

7. Microwave chemistry - Wikipedia

   en.wikipedia.org/wiki/Microwave_chemistry

   Microwave chemistry is the science of applying microwave radiation to chemical reactions. [1][2][3][4][5] Microwaves act as high frequency electric fields and will generally heat any material containing mobile electric charges, such as polar molecules in a solvent or conducting ions in a solid. Polar solvents are heated as their component ...
